Provided is a torque rod (1, 101, 202, 301) configured to be connected between a vehicle body (2) and an engine (3) to restrict a movement of the engine relative to the vehicle body. The torque rod includes a rod main body (11, 211, 307), and a bushing assembly provided at one end (14) of the rod main body. The bushing assembly includes a mounting bracket (21, 203, 303) configured to be mounted to the vehicle body or the engine via a bolt (22) passed therethrough in an axial direction, a magneto-elastic member (31, 204, 322) made of magneto-elastic material axially interposed between the one end of the rod main body and the mounting bracket, and a coil (32, 205, 323) configured to apply a magnetic flux to the magneto-elastic member.

An aspect of the invention provides a roll restrictor system for an automotive powertrain, comprising: a torque roll restrictor bracket configured for attachment to the automotive powertrain; wherein attachment is mediated by a bushing; wherein the bushing is provided within a bearing which facilitates rotation of the bushing within the torque roll restrictor bracket.

A roll rod for a vehicle includes: a bracket including a front insulator, which is connected to a power train, installed on one end portion; and a rear insulator assembly installed on the other end portion of the bracket. The rear insulator assembly comprises a rear insulator disposed on an inner side of a rear mounting portion formed on the other end portion of the bracket, and a core penetrating the rear insulator and fastened to a vehicle body.

A support rigidity of a torque rod with respect to a vehicle body is adequately increased. In addition to an upper bracket (52) and a lower bracket (54) for retaining the torque rod (66), the torque rod mounting structure includes a stay bracket (56) attached to the lower bracket (54) and the damper housing (24). The damper housing (24), the lower bracket (54) and the stay bracket (56) jointly form a closed cross section structure (58), and a retaining portion of the lower bracket (54) retaining the rear end (66A) of the torque rod (66) includes a part of the lower bracket (54) forming the closed cross section structure (58).

An engine assembly arrangement for a motor vehicle, with a drive assembly, which is mounted directly at a support element via at least one first fixed bearing. A support structure engages at the drive assembly, on the one hand, via a second fixed bearing and via a third fixed bearing that is spaced apart from the second fixed bearing, and, on the other hand, is articulated at the support element via a fourth fixed bearing.

A system and method using a mount assembly for attaching a powertrain to a structural member of a vehicle. The mount assembly includes a first compliant member, a second compliant member, a first fluid chamber, a second fluid chamber, a third fluid chamber, a pressure compliant membrane, and a valve. A fluid conduit interconnects the first fluid chamber with the second fluid chamber to allow a fluid to pass from the first fluid chamber to the second fluid chamber. The third fluid chamber has an opening in communication with the second fluid chamber and a vent port. The pressure compliant membrane seals the opening between the second fluid chamber and the third fluid chamber. The valve selectively seals the vent port in the third fluid chamber. A first stiffness profile of the mount assembly is selected by actuating the valve to open the vent port. A second stiffness profile of the mount assembly is selected by actuating the valve to close the vent port.
